Application lllcrl March ld, ltflllll.

, ltet'erence is had to the accompanying drawings, which illustrate thepreferred 'lt'orm ot the invention. though it is to be un derstood thatthe invention is not limited to a the enact details ot constructionshown and described, as it is obvious that various moditications thereotwithin the scope oit the claims will occur to persons shilled in theart.

lllolled metallic El hars are desirable as to compression memhers ot theside trusses ot steel trame railway hon cars because ot their greatstrength in any lateral direction and are also desirable as top chordsot girders l5 hecause ot their great strength (horizon tally) to stitlenthe girder against huclrling.

Such d hars are positioned with the web horizontal and the oppositelyprojecting danges positioned vertically.

llt is customary torivet additional meme hers to the side plate-whichmembers are also riveted to the root sheets. Such an p arrangementunnecessarily increases the weight ot the car as well as` the cost andalso 25 increases the time necessary to assernlole the car and to repairit. Punching and riveting are expensive in time and money.l

llt is customary to attach the roohng sheets to the upstanding verticaldange oit the Z har side plate so that the horizontal web ot the sideplate actually is a part ot' the root ot the car, hecause itis acovering tor that part ot the interior et the car between the outsidesheathing and the lining, therefore, l" such portion should he inclinedor sloped to ltorm a watershed and also to prevent the accuinulation otcinders, dirt, etc., which would hold moisture and cause oxidation.

llhe line ot impact ot cars in coupling and switching is through thecouplers, considerahly helow the center of gravity of the car,theretore, the inertia ot the car body tends to move it longitudinally.when the car is suddenly stopped or its speed quickly decreased. 'lhismovement is real and causes considerahle damage hy loosening thesuperstructure and the roof, etc. The inertia force ot any weight in thecar is in proportion to its vertical distance above the line of imlll,tlange to a carline and root sheets oit a rigid type out root..

pact (the coupler), therefore, any elimina- 501 tion ot weight in theroot or side plate materially reduces the weaving stresses.

'lhe sidewise swaying or swinging ot the car when moving over an uneventrack, crossu ings, switches, etc., increases or decreases 55 theangular relation oit the root to the side plate and has a tendency todistort or hrealr the connection along this line.

rllhe invention relates to a peculiar side plate tor a railway house carhaving means ou ot attaching a car root thereto and has tor its ohjectsthe reduction in weight ot the car; the reduction in the original aswell as maintenance cost; a stronger and more rigid connection to resistthe lateral weaving ot 65 the car; to increase the hearing area ot theroot' sheets upon the side plate; to increase the tunnel clearance hydecreasing the width ot" the car at the-eaves and to put the root sheetrivets in direct shear, and, turthermore, to malre a watershed ot thatpart ot the side plate torming part ot the root olf the car. lln thedrawings:

lTig. l shows my improved side plate wherein the upper llange andsloping weh are parallel and wherein the lower tlange and vertical wehare parallel lll ig. 2 shows a construction wherein the slope ot thelower web has heen altered. so that it is not parallel to the upperllange and the plane ot the vertical wel) has heen altered to make theheam symmetrical.

Fig. 3 shows the relation ot the upper 'lll llt

Fig. 4c shows the relation of the upper flange to a carline and rootsheets ot a deallole type of root.

Fig. 5 shows a detail view of the rolled section. I

My particular form ot' side plate com prises two obtuse angled welosl-2, one ot which (1) is sloped to 'torna a watershed and the other otwhich (2) is positioned suhstantially vertically. The' sloping weh isprovided with an integral downwardly projecting Harige 3 for attachmentozt the side wall 4 of. the car andthe substantially vertical flange isprovided with an integral flange for attachment of the roof framingelements and also the roof sheets, if: desirable.

Figs. 1 and 2 show my side plate having i the integral flange. (7 8) atthe upper part of the vertical web 2 projecting inwardly towardthej'car. llVhen` this flange projects inwardly the distance over theroof sheets is less, thereby not only saving in cost and weight of thecar, but also in increasing the tunnel clearances, and minimizing thepossible damage by side swiping.

I./"plane's The relative position aiid lengths of the webs andflangesmay be arranged to produce a symmetrical section, which is advantageous for1 simplicity of design and to avoid confusionin handling themember through the shop'and applying it to the car. In Fig. 1 the webs 1and 2 are of equal lengt-h and the flanges 3 and 7 are of equal lengthand "the angular relation of each flange to its adjacent web is thesame. The angular relation between web 1 and web 2 may vary and stillproduce a symmetricalsection. In Fig. 1 the vertical web 2 and thevertical flange Sare parallel, therefore, the "upper flange 7 and thesloping web 1 must be parallel inorder to produce a symmetrical section.The side plate shown in Fig. 1 is symmetrical about line A-A. Y c,

It may' bev desirable to increase the incli-- nation of the sloping webI1 (in order to produce 'a greater watershed, or for some other reason).Such a construction is shown in Fig. 2. In orderto maintain asymmetrical sectiony the position of the substantially vertical web J2has been altered until the angular relation of the flanges and theiradjacent webs is the same. The side plate in Fig. 2is symmetrical aboutline B-B.

4My construction may be used .with rigid steel roofs or flexible steelroofs. In a rigid steel roof the roof sheets and carlines (if any arerrigidly secured directly or indirect y to the side plate. Such aconstruction is shown in Figs. 1 and 3. Fig. 3 is a section on line 7-7in Fig. 1 and shows the relation between the carline 10, the roofVsheets 11 and the side late.

In a flexible roof the carlines 20 are rigidly secured `to the sideplate and the roof sheets are usually supported loosely by the sideplates (and perhaps other frame members) and-some sort of freelyflexible waterproof arrangement is used between the edges of the roofsheets 21 and the carline. A typical construction is shown in Fig. 4,which is a section along line 8-8 of Fig. 2.

g It isunderstood that a flexible or a rigid roof may be used with anyconstruction within this disclosure and still come within the. scope ofthe invent-ion.
